Squid´s Jet Propulsion Could Help People Overcome Needle Phobia

Seven percent of the population suffers from a severe fear of needles, known as trypanophobia. This issue has been addressed in various ways over the years. At MIT, researchers are adopting a creative approach to tackle this problem. They are utilizing the unique propulsion mechanisms of squid to guide micro-needles into the digestive tract for targeted injections into specific blood vessels.

The system operates using a small spring-powered device that can launch into tissue with little need for precision in positioning. Two different models have been developed for different purposes. The first, is a cylinder designed to deliver drugs in long, narrow spaces by launching needles from the sides. The second model resembles a lander and is used to deliver drugs to the bottom of the stomach.

Animal tests have already been conducted, and human trials are set to take place soon. With this new technology, the fear of needles may eventually be eliminated entirely.
